Valm, Alex M., Jessica L. Mark Welch, Christopher W. Rieken, Yuko Hasegawa, Mitchell L. Sogin, Rudolf Oldenbourg, Floyd E. Dewhirst, and Gary G. Borisy (USA) 108: 4152-4157 Bacteria in nature live not as isolated cells, but as members of a community in which many different kinds of bacteria live intermingled in complex associations. The spatial […]

Microbial community composition in sediments resists perturbation by nutrient enrichment

December 7th, 2012 @

A paper from Mitch Sogin and Hilary Morrison et al A microbial community’s functional capability—what it eats, what it produces—is thought by some to be more meaningful than the identities of its members.  Functional redundancy in bacterial communities thus allows communities to survive environmental disturbance even if the membership changes.  Others believe that microbial communities […]

A widespread class of reverse transcriptase-related cellular genes

December 7th, 2012 @

Publication by Eugene A. Gladyshev, Irina R. Arkhipova We describe a novel class of single-copy reverse transcriptase (RT)-related genes that do not constitute part of any mobile genetic element, and are clearly distinct from the only known non-mobile RT genes, the telomerases, which maintain chromosome ends in eukaryotes. These RT-like genes are of ancient origin, […]
